Just mount your drive:

 sudo mount /dev/sdb1 /mnt

from command line type:

sudo unetbootin installtype=USB targetdrive=/dev/sdX

unetbootin GUI will open with the selected drive already setted, also if it is ntfs formatted.

This is what worked for me

1. Delete partition in sdb1 in Gparted.
2. Reformat.
3. In terminal, type sudo mount /dev/sdb1 /mnt.
4. Run UNetbootin as normal.

Try this (worked well in my case):

1. (while Unetbootin is open and iso file mounted)
2. open GParted, go to GParted menu, select Devices and tick the path to your USB (/dev/sdb1)
3. Unetbootin should now recognize your USB drive and proceed with copying.
4. (you will perhaps need to eject and reinsert your USB before)

It is possible that the sequence you followed is as follows; your stick is formatted to contain a FAT32 file system.

1. You may have inserted the stick, selected your ISO, Unetbootin has detected your stick which reflects the screenshot of Unetbootin.

2. However, in the second step, you may have unmounted the stick manually or otherwise, but UNetbootim may not have refreshed

3. Now when you try to create the bootable USB, it cannot find where the stick is mounted because it has been unmounted.

Typically, I have noticed that the following steps work:

• Remove the bootable stick from the USB socket
• Launch Unetbootin, it would not show anything in the last row of fields, it would be empty.
• Now plug in the USB stick, it should detect and the contents will be automatically filled including the mount point
• Now proceed to create the bootable USB

I had the same issue. I am using Linux (Fedora) and I was formating the USB drive with the aplication "Disks" (default with this distro) and UNetBootin did not find the drive. I fixed the issue by reformating the USB using GParted. Now it is visible on UNetBootin. I don't know why, maybe some partition flag?

Deleting all files from my USB (even hidden ones, found with ctrl+h) helped Unetbootin find it in my case, I didn't even have to reboot Unetbootin.
